The Android 4.1.2, JellyBean update is now available on the Samsung Galaxy S Advance smartphone.

The software update began rolling out in countries such as Poland, Germany and Ukraine towards the end of last week. It will become available in other European countries in the near future. Users can access it through Samsung KIES software.

The software showed up on Android related websites such as 9to5 Google last week. Android Authority also reported on sightings of Android 4.3, JellyBean last month.

A Reddit user recently informed the site that the next major build of Android has been showing up in logs and reports as Android 4.3 JWR23B. Android builds normally appear in logs with their numbers followed by their letters. Both J and B are present in the software's codename, leading the redditor to believe that Android will at least announce one more major build of JellyBean before Key Lime Pie hits smartphones and tablets.

These sightings of the software apparently came from a Nexus 7 and a Nexus 4 being used by Google employees, according to AndroidCommunity. The site believes that the recent Android 5.0.1, Key Lime Pie sighting on the Motorola X smartphone was faked as server logs can be manipulated to show different names and numbers.

This new Android 4.3, JellyBean software will make its official debut at Google I/O. This does not mean that fans of Android should not expect some significant changes and new features, as Google is sure to enhance user-experience significantly.
